((1248- 351) standards, particularly as pedestals opsupports for conveyor tracks or movable sectionsthereof, asof the roller or wheel type, the track being inc1ined'.for dispatching by gravity, merchandise ;5, placed thereon. The track usually of. straight or curved sections so that the dispatchingjine and location can be readily changed or altered to meet difiere'nt dispatching destinations It is therefore necessary that the standards be adjustable for heighth variation.

An object of the invention is to provide .a standard of extreme simplicity in construction,

easily and cheaply fabricated from angleha-r and tube stock material, sturdy instructure and having a leg basepreferably in tripod arrangement,

resisting to shift and a stanchion or post adjustable within the base.

Another object is tov provide for a standard of a plurality of angle bars, an parallelism, traversing a tulbular support and secured and locked therein. by a cone pointed screw carried. by the support to intersect and oppositely force the-bars in binding engagement with the interior or the tube for a quick and secure heighth adjustment ,2

of the standardandto, form a simple and inex pensive structure of exceptional strength. .Various features and advantages and features of the invention will be more fully set forth in th following description of the accompanying drawing forming a part hereof and exemplifying a, preferred embodiment, in which: j Figure 1 is a side elevation of the improved adjustable standard.

Figure 4 is a section on line 44, Figure 3, Figure 5 is an end view of the head end of the stanchion.

Figure 6 is an enlarged section on line 6-4;, Figure 5.

Referring to the drawing, the standard as illus- -trated is principally constructed of sections of angle bar stock, consisting preferably of a tripod base I and a stanchion 2, adjustably mounted within the base. The base comprises a plurality of legs 3, of angle bar sections, in tripod arrangement, with the apex of the bars outward adapting the flanges for one end of the bars to straddle and bear against the exterior of a tube section 4, as a hub-or axis for the base, through which the stanchion traverses and to which it is clamped. The legs are preferably welded to the hub 4, and toward their lower end are tied together, against an aperture'fi, therethrough, coaxially with the hub as a clearance for the lower end of, the stanchion, so as not to limit its descent adjustt-s v I The stanchion is composedoi a. pair of companion angle bar sections 1, 1, preferably arranged with they flanges opposingeach other and slightly spaced apart, and both, at their upper end are :joined to. a transversehead bar 8, preferably at a point central of the length of the head bar. The head bar, correspondingly, comprises an, angle fbar section, with. its apex upward,

whereby the flanges of the bar "straddle theu'pper end of the stanchion bars and the parts welded together.

.The stanchion composed of a plurality of parallel angle bars is extremely sturdy, capable of sustaining heavy loads without flex, aside from its simple. and economical rabrication.,. The bars in their slightly spaced or separated relation provide a longitudinal opening for the full length of the 'bars for the reception of a pair of guide rods 9, 9, diametric of the hub and at their opposite ends fixed thereto. The rods 9, non-rotatively confine'the stanchion within the hub and govern its insertion therein, so that the spacing or'line of division is always brought and maintained in alignment and registration with the cone pointed end of a clamp screw [0. The clamp screw. I0, has its outer end bent at an angle to provide a crank hand hold.

The cone pointed end of the clampscrew I0, wedgingly engaged with the edges of relative opposing flanges of the angle bars of the stanchion and in tightening spreads the bars apart at one longitudinal end, while the opposite ends are maintained and in bearing contact with the struts or separator rods 9, within the hub, to fulcrtun thereon and force the apexes of the bars into impinging contactwith the interior or bore of the hulb, binding the parts together for the full constanchion under heavy loads imposed thereon,-

an'dmore effectively than is possible by the conventional method of having the pointed end of.

a clamp or set screw engaging against a flat or peripheral surface of a stanchion. 55 With one flange of each angle bar in bearing of tripod form having its legs fixed to and extending from a central hub, and a stanchion traversing the hub and composed of a pair of spaced bars fixed together at one end and the hub having a clamp screw for wedging between the bars for forcibly binding the same within the hub.

2. An adjustable standard, comprising: a base having a' centralvertical hub, a stanchion composed of a pair of angle bars traversing the hub and disposed in opposing relation to extend their The upper end of the bars 1,1, of the stanchion I are fixed together and determinately spaced by a tie plate ll', combining the same asan integral,-

unit, including the transverse head bar The standard is equally applicable for adjust-1 ably supporting either curved or straight roller conveyor track sections, is comparatively light v 3. An adjustable standard, comprising: a base apexes. outward, and a clamp screw carried by the hub having a conical end engaged between the bars to spread them apart and force their apexes int'o biting contact with the hub.

having a vertically extended hub, the hub havin weight and exceptionally strong. A conveyor line can be set up and adjusted for proper pitch in a few minutes and a change in the line can be readily affected to accommodate for different loading and unloading destinations. The hubof the base isillustrated as provided with a pair of guide rods'or struts 9, 9, respectively located at opposite ends of the hub, it however has been experienced that asingle strut preferably located at the upper end of the hub will suffice. e

In the preferred form of tripod base, the-legs are not relatively uniformly spaced about the hub, and in plan one pair are in closer relation and correspondingly obliquely to the head bar of the stanchion so as to stretch out as from one side thereof while the third leg is at right angles tothe head bar and asextending from an opposite side of the head centrally opposing to the others as a pair. This arrangement offers greater stability against tilt. The struts or guide rods 9, are disposed to extend in a direction in relation to the legs to insure insertion of the stanchion with the head bar extending in direction at an angle thereto and thereforeappropriately to the leg set up.

Having described my'invention, I claim: 1.- An adjustable standard, comprising: a base ing struts diametrically across its bore, a stanchioncomposed of a pair of angle bars, traversing the hub and respectively at relative opposite sidesof the struts and a clampscrew carried by and extended into the hub in alignment with the struts for engaging with the bars at a lineoi division thereof to simultaneously force the same outwardly into binding contact with the interior hub, the struts governing the insertion of and maintaining their line of division in-registry with the clamp screw.

I 4. An adjustable standard, comprising: a base of tripod form having avertically extended hub with a strut extending diametrically through its bore,a stanchion of T-head form composed of a-pair of spaced parallel bars at one end joining with a transverse head bar, the parallel bars slidably engaged through the bore of the hub of the base, respectively at relative opposite sides of the strut, and means extending into the hub for engaging the bars at a line of'division to simultaneously 'force the same outwardly into binding contact "with the hub, the strut 'governing the'insertion of the bars with their line of division in registry with said means and appropriately directioning the T-head of the stanchion to the legs of the tripod base.
